In regards to price action, the following is copied from the link above:
As protection against spamming bots that automatically register names, there will be a base price and floor price one has to pay.
The base price and floor price depend on the number of characters in your domain name.
Base price — The price at which begins the bidding.
Floor price — A price that cannot go lower than this threshold.
Number of characters: Base price/floor price.
4 characters: 1,000/100 Toncoin
5 characters: 500/50 Toncoin
6 characters: 400/40 Toncoin
7 characters: 300/30 Toncoin
8 characters: 200/20 Toncoin
9 characters: 100/10 Toncoin
10 characters: 50/5 Toncoin
More than 11 characters: 10/1 Toncoin
Every 30 days, the current base price will decrease by 10% until it reaches the floor price.
